This is the fire extinguishers used on commercial airlines. It is a non used bottle with burst disk intact and gauge reading 500psi. It will require a squib(explosive charge), to make complete. These things dump full content in a second or so. They are very fast acting and can be dangerous if not installed properly. Unfortunately I am unsure of the laws on how to ship, so buyer must arrange pickup or shipping.
Item sold as is for parts with no returns accepted. Thanks for looking!
